After they left the Hornitos Cinco de Mayo party, las hermanas de Hilton strolled around West Hollywood hitting the clubs last night with their respective boyfriends. At one point, they even stopped by the Crown Club - think they got a chance to party with Lauren Conrad?

We'd also like to call a little attention to Paris' dress - and the way it puts at least some of the costumes worn to the Met last night to shame! See? Who needs to try that hard?

In fact, we put together a whole gallery of Paris (and the rest) looking great - check it out below!
